What is YARA?

YARA is a tool aimed at helping malware researchers to identify and classify malware samples. It allows you to create descriptions of malware families (or whatever you want to describe) based on textual or binary patterns. A YARA rule consists of a set of strings and a boolean expression. YARA rules are commonly used for malware analysis, threat hunting, and incident response to identify malware samples or other malicious artifacts based on specific patterns or characteristics.
